Worked on the redis/redis repository to refactor the Async Slot Migration (ASM) component, focusing on improving modularity and maintainability within the codebase. The approach involved removing the long-lived source_node pointer and introducing a clusterLookupNode function, which decoupled ASM from the core Cluster module and established clearer boundaries between components. This architectural change, implemented in C with an emphasis on software architecture and system programming, aimed to reduce cross-module dependencies and facilitate safer, more maintainable future changes. No explicit bug fixes were recorded during this period, as the primary focus was on targeted refactoring to enhance code isolation and testability.
